Essentials of Coherent Optical Data Transmission
Application Notes
Data centers are being built across the globe enabling medium and smaller size enterprises to also store and analyze big collections of structured and unstructured data in the cloud, in order to optimize the supply chain, marketing activities and more. The storage and analysis capacities are in place but the more critical question is if the infrastructure outside of the data centers can keep up the pace. The explosively growing amount of data is becoming an enormous challenge for our backbone networks. If they don’t want to become the bottleneck of the future, the spectral efficiency needs to be increased in fiber optical networks. Today, fiber optical infrastructure and signal concepts need to support data rates of 100 Gbit/s, soon 400 Gbit/s and even higher. This is a problem for traditionally applied data coding schemes.
